FIBER-CASE RAILWAY-TORPEDO.

Specification of Letters Patent.

Patented J an. 18, 1916.

Application filed May 28, 1915. Serial No. 31,034.

Case Railway-Torpedoes, of which the following is a specification, referencebeing'had therein to the accompanying drawing.

My invention relates to improvements in fiber case railway torpedoes.

The object of my invention is to provide a case having an open face in which the explosive tablet is placed, and a disk and sealing composition forming the top of the case.

Another object of my invention is to provide means whereby the rail-attaching strap is more efi'ectively secured to the case and whereby a water-tight torpedo is produced.

A still further object of my invention is to provide a torpedo of this character having certain details of construction and combination of parts hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a perspective view of my improved torpedo. Fig. 2 is a vertical sectional view of Fig. 1. Fig. 3 is a vertical sectional view of Fig. 1 taken on the line atright angles to Fig. 2. Fig. 1 is a perspective view of the several parts forming the torpedo in their separated relation. Fig. 5 is a perspective view of a modified form of torpedo. Fig. 6 is a transverse vertical sectional view of Fig. 5. Fig. 7 is a transverse vertical sectional view of Fig. 5 taken at right angles to Fig. 6. Fig. 8 is a'perspective view of the several parts forming the torpedo in their separated relation.

Referring now to thedrawings, 1 represents the case of my torpedo which is preferably of a saucer shape and having in its bottom 4 the two slits 2 and 3. The bottom between the slits 2 and 3 is provided with the downwardly pressed portion 5 forming a space through which the rail-attaching strap 6 is threadedas fully shown in Fig.

. of the drawings.

The body portion or case 1 has a vertical wall 7 and after the strap has been applied, as shown in Fig.4 of the drawings, cement is placed on the upper face of the bottom of the case, and the disk 9 is forced down upon the cement which forces the cement downward around the slits 2 and 3 above the rail-attaching strap 6. The cement is also forced upwardly around the edges of the disk 9. A band 10 is placed around the vertical wall 7 of the case with its upper edge slightly above the upper edge of the vertical wall 7. The explosive tablet 11 is then placed in the torpedo and a cement and sealing composition 12 is placed in the case on the upper face of the explosive tablet 11 and down around the oblique wall 13 thereof and filling the space above the explosive tablet over the upper edge of the vertical wall 7 of the case. 'A disk 14 is forced downwardly upon the cementing and sealing composition 12 which forces a portion of the sealing or cementing composition upwardly around the edge of the disk 14: and completely seals the torpedo. By this structure and arrangement of parts it will be seen that the torpedo above and below the explosive tablet 11 is completely sealed and the band 10 prevents any spreading of the vertical wall 7 of the case. The disk 14, as heretofore described, is forced down until it rests upon the upper edge of the vertical wall 7 of the case and therefore cannot be forced down a suificient distance to force all of thecement or sealing composition from the upper face of the explosive tablet 11. The disk is is also approximately of a thickness equal to the distance the band 10 extends above the upper edge of the vertical wall 7 of the case, and whereby the disk when in place is flush with the upper edge of the band as shown in Figs. 2 and 3.

In the modification shown in Figs. 5, 6, 7 and 8 instead of having the bottom a of the body portion 1 provided with the slits 2 and 3, I provide the bottom with an opening 15 and instead of employing a fiber disk 9, I employ a metal disk 16 having an opening 17 centrally arranged. The rail-attaching clip 18 is provided with an opening 19 and a rivet 20 extends upwardly through the openings 19, 15 and 17 and is riveted upon the upper face of the disk 16. This as will be understood, firmly locks the rail-attachwithin the case, a. sealing composition filling the case above the explosive tablet, and a disk embedded in the sealing composition.
